Differences Between the 2017 and 2019 Total Solar Eclipses


The recent 2019 total solar eclipse was a spectacular sight. The event was visible to parts of Chile and Argentina in South America before sunrise on July 2nd, 2019. There were some notable differences between this total solar eclipse and the last one in 2017.

Unique Eclipse Experiences

The Great American Eclipse of 2017 was an exciting event for scientists and ordinary people. Watch parties were set up around the country to view the sight. The just ended eclipse was another very exciting one, but with a few differences.

A total solar eclipse happens when the Moon blocks the Sun. At the highlight of the event is the moment of totality known as the corona. Although the fundamentals may be similar, different conditions create largely different celestial events. In the 2019 event, scientists set out to study some important details about the Sun and the atmosphere. This includes how the magnetic field operates and how heat moves in the corona.

Scientists and astronomers were prepared to observe the eclipse bearing in mind the major differences between 2017 and 2019. One of these is that less or limited information could be obtained about the corona due to low solar activity. Compared with 2017, the sun is experiencing even lower magnetic activity this year. This means that, although the corona was visible more clearly, it was more difficult to spot any masses escaping from this corona.

Another difference in the last two total solar eclipses is that the 2017 eclipse crossed over more land. It was visible over a distance of around 4,600 kilometers from Oregon to South Carolina. On the other hand, the path of the 2019 eclipse was more visible over the southern Pacific Ocean. It covered a distance of about 2,000 kilometers on land between Chile and Argentina. Finally, the recent eclipse was lower in the sky, making it a little more difficult to observe.
